Abundance in earths crust - 9 parts per billion by weight
Background -
No one person is credited with its discovery
It has been known since ancient times
Origin: from the german word "bisemutum"
Belongs to the nitrogen family
Used in fuses, pharmaceuticals, fire sprinklers
Chemical Properties -
Reacts with oxygen to form Bi2O3
Reacts with chloride to form BiCl
Bismuth is commonly used in fire sprinklers. Since bismuth aloys have low melting points, it makes them ideal for many uses. When the smoke rises from the flames, it melts the bismuth alloys, which allow the s[rinkler system to detach, thus letting the water spray.
